摘　　要：本文提出了一种SMA-滚珠碟簧隔震装置,该装置将滚珠隔离水平地震,SMA丝增大装置的复位、消能能力及碟簧隔离竖向地震相结合,形成一种新型三维隔震装置。完成了该装置的性能试验,试验结果表明:SMA数量增加可以增大隔震装置的水平刚度及阻尼比,装置具有更好的隔震性能,凹形板间的摩擦系数对隔震性能有一定的影响,碟簧的设置可提供较好的竖向隔震效果。A SMA-ball disc spring isolation device is presented in this paper. Combining with ball isolation horizontal earthquake,SMA wire＇s resetting and dissipation ability and dish spring isolation vertical seismic,a new three-dimensional isolation device is formed. The device performance test is completed. Test results show that： the increasing of SMA number significantly increases the isolation device＇s horizontal stiffness and damping ratio,the device has better isolation performance,the concave plate ＇s friction coefficients have some influence on the device＇s isolation performance,and the disk spring has good vertical isolation effect.
